The File Title Updater plugin streamlines title management across different parts of an Obsidian note by keeping the filename, frontmatter title, and first-level heading in sync. It offers flexible commands that let users choose a preferred source of truth—whether that's the file name, metadata, or heading—and updates the other two accordingly. With built-in smart detection, the plugin avoids redundant operations if the titles are already aligned. It also handles formatting niceties, such as inserting appropriate spacing and cleaning up illegal characters in file names.
